SINGLE BURNER FOR VAPOR-LAMPS.

SPECIFICATION forming part of Letters Patent No. 686,086, dated November 5, 1901. Application filed April 7, 1900. Renewed July 18, 1901. Serial No. 68,889. (No model.)

To all whom it may concern;

Be it known that I, ARTHUR KItrsoN, a subjectof the Queen of Great Britain, and a resi. dent of Germantown, (Philadelphia,) county of Philadelphia, State of Pennsylvania, have invented certain new and 'useful Improvements in Single Burners for Vapor-Lamps, of which the following is a specification.

My invention relates in general to vapor- |o burningapparatns, and more specifically consists of an improved single burner for vaporburning apparatus for use in lamps employing the well-known Welsbach incandescent mantle. In lamps of high candle-powerof I5 this type two or more mantles have heretofore been employed. Of course in such construction each of the mantles to a certain extent interferes with the rays of light given oif from the other, and, furthermore, the pos- 2o sibility of breakage in cleaning is twice as great where two mantles must be removed and replaced. I have therefore invented the improved form of single-burner apparatus herein described, which is designed to be mm ployed with a special large mantle. In such construction points which have to be care- 1 fully kept in view are the thorough mixing of the vapor and air in the larger burner and the delivery of the same evenly to all parts I moves up through said burner-tubeandissues of the larger mantle.

The preferred form of apparatus enlbodying my invention is illustrated in the accompanyin g drawing, in which the standard form of lamp, havinga casing 1, consisting of chimney, annular supporting-frame, and hemispherical glass globe, is shown in section.

Across the chimney there extends the usual vaporizing-tube 2, which discharges a jet of vapor. into the upper end of the mixing-tube 4o 3. This mixing-tube is curved to one side,

so as to have its lower end extending in a horizontal direction, and on it is mounted the burner 4 and above that the mantle 5.

The burner 4 consists of the upright cylinder 6, across the upper end of which extends the usual wire-gauze 7, the same being retained in position by the annular cap 15 or by any other convenient means. Asolid button 8,

preferably of metal, is supported centrally of said gauze by means of the screw 9 or other 56 convenient means. The lower end of the burner-cylinder 6 is closed by a solid head, preferably made in the form of an outwardlydished plate 10, as shown, and at the lowest point of said dished head the outlet-valve 11 5'5 may be placed. The gauze 12 is stretched across the burner-tube 6, below the level of the mixing-tube 3, and preferably said gauze is located at the junction of the burner-tube and the dished head 10. The mixing-tube 60 extends across the burner-tube, being of less diameter than said burner-tube, and has its end closed, as by a head 14. The said mixing-tube has a discharge-opening in its under side, (shown at 13,) through which a down- Ward discharge of the vapor; and air occurs over the center of the gauze 12.

The mode of operation of my invention is evident from the foregoing description. The jet of vapor issuing from the vaporizing-tube 7o 2 entrains the necessary amount of air into the mixing-tube 3, and the mixture passes down said tube and out through the discharge-opening 13. Being thrown down upon the gauze 12, itis thoroughly mixed together and distributed evenly throughoutthe entire cross-section'of the. burner-tube It then through the annular discharge-opening between the button 8 and the cap 15 of the burner. A cylindrical or conical flame of the Argand type is thus formed, which burns under the large mantle 5, heating the same to intense incandescence throughout its entire area. W

The advantages of my invention comprise the increased efficiency, reduction in cost, and reduction in loss by breakage resulting from the use of a single mantle in place of the two mantles heretofore employed. The de- 0 livering of the combustible mixture in an annular discharge adjacent to the sides of the mantle also economizes fuel and produces an efficient heating of the mantle. The gauze 12 not only serves to distribute the mixture 5 evenly throughout the large burner-tube 6 and prevent the formation of eddies, but also serves to collect any particles of unvaporized oil, and retain the same in a position where the combined action of heat and air currents tend to produce their reevaporation. Any surplus quantity of oil collecting on the gauze 12 drops through onto the dished head 10 and if not reevaporatcd can be drawn oif through the valve 11. I have found the construction of the discharge-orifice 13 and its downward discharge to be necessary for the even distribution of the combustible mixture throughout the large burner-tube 6, and this when taken in connection with the gauze 12 produces improved results.

Itis evident,of course,that various changes could be made in the details of the apparatus shown in the drawing without departing from the principle of operation described in the specification. The proportions of the parts and their shapes and the manner of attaching them together might be varied without departing from the spirit and scopeof my invention. Also certain features of the invention might be employed without using other features described; but all such modifications I should still consider within the limits of my invention.

Having, therefore, described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. In a vapor-burning lamp the combination of a burner in the form of a cylinder with its lower end closed, and a mixing-tube entering at the side of the cylinder and having a discharge opening downward toward said closed lower end.

2. In a vapor-burning lamp the combination of a burner in the form of a cylinder with itslower end closed, and a mixing-tube entering at the side of the cylinder and having a discharge opening downward toward said closed lower end, together with the gauze stretched across the burnertube below the mouth of the mixing-tube.

3. In a vapor-burning lamp the combination of a burner comprising. a short cylinder with its lower end closed by an outwardlydished head, and a mixing-tube entering at the side of the burner-tube and having a downward discharge opening located over the center of the dished head.

4. In.a vapor-burning lamp the combination of a burner comprising a short cylinder with its lower end closed by an outwardlydished head, and a mixing-tube entering at the side of the burner-tube and having a downwarddischarge opening located over the center of the dished head, together with the gauze stretched across the burner-tube at the point where the head joins the tube.

5. In a vapor-burning lamp the combination of a burner in the form of a vertical cylinder closed at its lower end, and a mixingtube of smaller diameter which enters one side of the burner-cylinder, extends across the same, and has its end closed, with a discharge-opening in its under side.

6. Ina vapor-burning lamp the combination of a burner in the form of a vertical cylinder closed at its lower end, and a mixingtube of smaller diameter which enters one side of the burner-cylinder, extends across the same, and has its end closed, with a discharge-opening in its underside, together with the gauze stretched across the burnertube below the level of the mixing-tube.

7. In a vapor-burning lamp the combination of aburner in the form of a cylinder with its lower end closed, and a mixing-tube entering at the side of the cylinder and having a discharge opening downward toward said closed lower end, together with the gauze across the upper end of the burner-tube and the button located centrally thereof, whereby an annular discharge-orifice is formed for the combustible mixture. I

8. In a vapor-burning lamp the combination of a burner comprising a short cylinder with its lower end closed by an outwardlydished head, and a mixing-tube entering at the side of the burner-tube and having a downward discharge opening located over the center of the dished head, together with the'gauze stretched across the burner-tube at the point where the head joins the tube, the gauze across the upper end of the'burnertube, and the button located centrally of said last-mentioned gauze.
